As sir_pudding said.
Things were going pretty well this year, but derailed a bit recently because of my moving house/office, and various subsequent things. However, the base program is looking pretty solid, I think.
I post things to a blog about it:
https://www.misersoft.com/gca5/. There are build notes when I make a new build, and a couple preview looks I've done along the way.
There are also some posts about it around here, I just don't have them handy.
Feel free to ask questions or post suggestions or whatever. GCA is pretty user driven, for the most part.
